Air Gear Motor Gast and air-powered Gearmotors are available in both lubricated and oilless models. Known industry-wide for their rugged construction and reliability.
These air motors and gear motors are used in many industrial applications, from mixing equipment to running pump drives.
- Self-sealing vanes take up their own wear, ensuring consistent output for thousands of hours of use.
- Variable speed capabilities allow flexibility and versatility in any number of applications.
- Cool-running operation means air motors can be used in ambient temperatures of up to 250° F (120° C)
- Non-electrical operation reduces the possibility of explosion from igniting flammable gases.

- A Bearings
- Ball bearings used on input shaft; tapered roller bearings used on the output shaft.
- B Case
- Fine close-grain cast iron; crankcase sealed; duplex-milled for parallelism of mounting surfaces.
- C Worm
- 8620 alloy steel thread rolled to give uninterrupted grain pattern; carburized and hardened after rolling; high- burnish contact surface from rolling reduces friction coefficient for less heat generation, lower power losses. In large sizes, worms are cut, hardened, and ground to a good micro-finish, providing the ultimate in efficiency and torque capacity.
- D Worm Gear
- Forged bronze; geometry and high helix angle give maximum beam strength, high efficiency.
- E Cap Screw
- High-strength fasteners with corresponding torque specifications prevent loosening or breaking.
- F Seals
- Double-dipped and spring-loaded for leak proofing; tested to ensure compatibility with lubricant.

More reasons why you should switch from electricity to air.
If you compare Gast Air-Powered Gearmotors with any electric-powered Gearmotor, there’s really no comparison. Here’s why:
- Size for size, weight for weight, you can’t beat a Gast Gearmotor. A typical rotary vane air motor – the type used in Gearmotor – developing 21 /2 hp (1,9 kW) at 1800 rpm and 90 psi (6,2 bar), weighs just 17 pounds (7,7 kg). A comparable electric motor maybe two or three times heavier.
- More speed control.
- You can’t get more precise turning power than with a Gast Gearmotor. In applications where you need variable speed – like bolt tensioning equipment or rock drilling rigs – one-speed electric motors just won’t fit the bill. Precise lifting, lowering, or turning is simple with Gast Gearmotors.
- More flexibility.
- More than most standard electric-powered gear reducers can provide. Gast Gearmotors give you infinitely variable turning power from 73 to 5200 lb. in. (8 to 587 Nm) of torque. And Gast Gearmotors are instantly reversible through easy valving in the airline.
- More configurations.
- That makes it easier for our product to work for your product. Our gear motors are available in four mounting configurations.
- More life.
- Unlike electric-powered gear motor, there’s no chance of burnout with a Gast Gearmotor. They can be stalled indefinitely with no heat buildup. They’re nonelectrical sparking, too, which makes them ideal for use in potentially explosive environments – places where you couldn’t even consider electricity
